Filter by:Post-Traumatic Stress Disorder (PTSD) is an anxiety disorder that follows exposure to an extremely traumatic stressors. PTSD is associated with serious symptoms. While numerous approaches have been used to treat PTSD, these treatments have several limiting factors. This study will evaluate a combination of the drugs clonazepam and paroxetine for the treatment of PTSD symptoms. The main goal of treatment in patients with PTSD is to significantly reduce symptom severity and improve functioning. While numerous approaches have been used to treat PTSD, these treatments are limited by variable response rates, up to a 6-week lag period before clinical response, and sub-optimal side effect profile, including possible worsening of anxiety and insomnia prior to clinical response. The proposed study will examine whether combined treatment with a benzodiazepine (clonazepam) and a selective serotonin reuptake inhibitor (paroxetine) in patients with PTSD will accelerate the onset of clinical response. A second goal is to evaluate whether the rapid and clinically meaningful benefits are sustained until the end of the study, despite tapering off the benzodiazepine at the midpoint of the study. The safety and tolerability of a combination of paroxetine and clonazepam will be compared to paroxetine and placebo (an inactive pill) in the treatment of PTSD. Participants in this study will be randomly assigned to receive either paroxetine plus clonazepam or paroxetine plus a placebo for 12 weeks. Participants will have weekly clinic visits for the first 4 weeks of the study and every other week for the last 8 weeks. Symptoms of PTSD, anxiety, and depression will be evaluated and drug side effects will be noted during the follow-up visits.
The primary goals for this investigation are to quantify: (1) fluctuations in PTSD symptom reports when assessed at bi-weekly intervals; (2) change in PTSD symptoms associated with stressful life events; and (3) change in PTSD symptoms associated with perceived social support.
This is a double-blind, placebo-controlled, randomized study lasting 8 weeks. Purpose of the study is two-fold: first, to use a pharmacological agent to treat symptoms of PTSD, and second, to explore neurobiological mechanisms of action of guanfacine.
This study will evaluate naltrexone and cognitive-behavioral therapy treatments for alcohol dependence and post-traumatic stress disorder (PTSD). Subjects will be randomly assigned a 6-month treatment of either: 1) naltrexone alone, 2) naltrexone with PTSD psychosocial therapy, 3) a placebo with PTSD psychosocial therapy, or 4) placebo alone. An enhanced medication management intervention will accompany all treatment conditions. Follow-up assessments will be completed at 9 and 12 months after treatment.
Posttraumatic stress disorder occurs in patients who have experienced, witnessed or have been confronted with an event involving actual death or the threat of death, serious injury, or the threat to physical health and felt fear, helplessness, or horror. As a result, patients continue to re-experience, recollect, dream, or have flashbacks about the traumatic incident. Research on PTSD continues to show metabolic changes in specific areas of the brain in patients diagnosed with PTSD. For example, neuroimaging studies (functional MRI and PET scans) reveal that blood flow and glucose utilization increases in the right frontal, limbic, and paralimbic areas of the brain in patients with PTSD, particularly when they are recalling the traumatic event associated with their symptoms. One potential method for interfering with the neuronal circuitry associated with traumatic memories is through the use of repetitive transcranial magnetic stimulation (rTMS). This technique involves the placement of a cooled electromagnet with a figure-eight coil on the patient's scalp and rapidly turning on and off the magnetic flux. This permits non-invasive, relatively localized stimulation of the surface of the brain (cerebral cortex). The effect of magnetic stimulation varies, depending upon the location, intensity and frequency of the magnetic pulses. Preliminary clinical data shows that low frequency rTMS stimulation leads to a decrease in regional cerebral blood flow. This study is designed to determine if rTMS stimulation in patients diagnosed with PTSD leads to symptomatic improvement, reductions in blood flow to specific areas of the brain, and improvements in the regulation of the autonomic nervous system.
This study will investigate the use of sertraline (Zoloft) to decrease alcohol consumption and crime-related post-traumatic stress disorder in those individuals with both disorders. This will be a 12-week, placebo-controlled, double-blind outpatient trial. All subjects will receive cognitive behavioral therapy in addition to a placebo or sertraline. Comprehensive evaluation will be done at study entry; treatment termination; and 6, 9, and 12 months after study entry.
The purpose of this study is to compare the effectiveness of two psychological therapies used to treat PTSD in children who have recently been sexually abused: Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) vs Child Centered Therapy (CCT). Child sexual abuse is a common experience that has serious mental health consequences, including the development of PTSD and other abuse-related problems. All children will be assigned randomly (like tossing a coin) to receive either SAS-CBT or NST at each of two sites. In addition, the parents and the child will receive individual therapy for 12 weeks. The child will be monitored to evaluate his/her response to therapy. Assessments will take place before and just following treatment, and then 6 and 12 months post-treatment. A child may be eligible for this study if he/she: Has been sexually abused, is suffering from PTSD as a result of the abuse, and is 8 to 14 years old.
The purpose of this study is to compare two treatments for post-traumatic stress disorder (PTSD): fluoxetine (an antidepressant) and Eye Movement Desensitization and Reprocessing (EMDR, a psychological treatment in which the patient is led through the memory of a traumatic experience in order to heal him/herself). There are a variety of therapies used to treat PTSD, but the effectiveness of medication alone vs an exposure treatment, such as EMDR, has not been tested. Patients will be assigned randomly (like tossing a coin) to one of three groups for 8 weeks of treatment. Group 1 will receive fluoxetine; Group 2 will receive EMDR; and Group 3 will receive inactive placebo. Patients will then stop treatment and have evaluations, including psychological tests, at the time treatment is stopped, 8 weeks later, and at 6 months. An individual may be eligible for this study if he/she: Has PTSD and is 18 to 65 years old.
